The invention relates. to improvements in t'ypewriting-accounting. machines, and. particu-v larly to the ascertainment and the carrying. for-' ward. of balances.

Up to the. present: the newly ascertained balance was. printed numerically and on being carried forward as an oldbalance this numerifially represented amount was read 011 and by striking the corresponding figure keys was introduced into the machine. In. these operations errors in reading on the amount resulting in typing. errors could. easily occur which might remain undiscovered for a longtime and necessitate a troublesome. investigation and thereby a great. loss of time.

According to-the invention this disadvantage is now overcome, in that the newly ascertained balancein writing out,. e. g.,, in total-taking, isrepresented. by symbols serving as control operations, whereby these. symbols on the next bookkeeping operation for the purpose of carrying forward thisvalue as an oldv balance, automatically control the registration. and. printing mechanisms. An automatic writing-out of the new'balance and an automatic bringing-in oi the. same as an old balance" is thus rendered possible. so that typing errors are completely excluded.

In the drawings one form of construction of the subject of the invention. is illustrated by way or. example.

This invention is applied to a power-driven typewriting-accounting machine equipped preferably with' a decimal tabulating mechanism, such as disclosed in United States patents'to Kammel, No. 2,186,642, issued January 9, 1940; No. 2,236,642; issued April 1, 1941; and No. 2308924 issued January 19} 1943, and the following description is to be read with reference to the patented disclosures.

On the depression of the total taking key I (Figs. 7 and 16) for the cross footer CT (Figs. 1, 10, 1'6 and 18) the face 2 (Fig. 7) of the lever 3 acts onthe nose 4 (Figs; 1, 2, 5 and 7) of the flap 5. Thus, the flap 5-is swung round the pins lza, Il a (Figs; 3- and 4), which are Joumaled in 7 control key I.

the levers I2 and II, in the clockwise direction against the action of the spring 6 '(Fig. 2). Consequently the lug 1 of the flap 5 slides off the edge 8 of the bearing 9, which is formed as a stop I0. As soon as the stop I of the bearing 9 releases the lug 1 of the flap 5, the levers I I, I3, 12 which are rigidly mounted on the shaft I4 and the shaft I4 are rocked round the pins Ilb and 9b, rigidly mounted on the bearings 9 and 9a, in the anti-clockwise direction under the action of the spring I6 engaging with the three armed lever I in consequence of the pin and slot connection I4a, I5a. The three armedlever is thus rocked round the shaft 30 in the clockwise'direction.

General mechanism The transversely extending parallel rails 303 and 304 fixed to the machine frame 302 (Fig. 3) support the paper carriage I40 already mentioned together with its platen I52. The front bar of the carriage frame 305 of the paper carriage I40 carries a supporting rail I86 along which the column totalizers TI to T6 are adjustably secured. table 301 attached to, and projecting forward horizontally from, the calculating mechanism housing 306 is provided with ways to slidingly accommodate a traveling bed 308, which carries a cross -footer Ct. In front of the calculating mechanism 306 are located the figure typing keys .309, the letter typing keys 209, the space key 3l0, the decimal tabulating keys I85 and the calculatingkeys I98. To the left of the calculating keys I98 (Fig. l) is arranged the TT key and to the right of the calculating keys I98 the total takin To the right of the letter typing keys 209 are located thecase-shift or type-shift key "SK and the key PS for continuous type- .shift. These parts and their arrangements are sufficiently known. and are 'here referred to, only .to complete the description.

The body or frame-work 302 of the machine supports thetraveling carriage 305. A platen carriage is supported by the traveling carriage to travel therewith in letter spacing direction and return, the platen carriage also having a limited vertical movement or case shift relatively to the traveling carriage. The platen I52 is journaled in the platen-carriage. the platen being mounted -on,a platen shaft extending through the end plates 3I I, 3I2 of the platen frame and provided at its outer ends with the usual finger knobs 481 (Fig. 1).

Value punching mechanism To the inner faces of the respective right and left end frames 3| I, 3I2 (Figs. 1, 3, 5 and 12 to 15 inclusive)'of the case shift frame in which the platen I52 is journaled, theend plates 3I3,

3 I4 of a value indicating and sensing mechanism are secured at 3I5 and 3 I 6 (Fig. 3).

Rails 3I1, 3I8 preferably tubular in cross-section, firmly connect the respective end plates 3I3, 3 I4 to form a rigid framef A pair of horizontally arranged stretcher and guide bars 3I9 and 320 (Figs. 1 and 3-5) extend vbetween the opposite end walls 313, 3| 4 of the framefor the value indicating and sensing mechanism. These guide bars 3I9, 320 are located 1 in a plane above the platen and are closely juxtaposed with their apposed-sides faced off to form a vertical leading-in slot 323 coinciding or in alignment with a tangent touching the platen at the printing line thereof. Fastenings 32I, 322 .(Fig. 16) connect the stretcher and guide bars at points beyond the ends of the leading-in slot the tubular rail 3 I6.

edge of the rearmost guide bar 3I9 is extended above the corresponding edge of the foremost bar 320 and is beveled to facilitate the insertion of the record material into the leading-in slot.

To enable the guide bars 319, 320 and their associated mechanisms to travel transversely of the machine relatively to the rigid frame 3 I 3, 3 I4, 3I1, 3I8, bosses 324, 325, 326 (Fig. 16) arranged in spaced relation on the front face of the foremost guide bar 320 carry forwardly projecting studs 321, 328 and 329 on which coned supporting rolls 330, 331, 332 (Figs. 3, 5 and 15) are journaled. The studs are arranged in staggered relation, the central roll 33I being in a horizontal plane below the end. rolls 330, 332, to take over Also rolls 334 and 335, Figs. land 3, are journaled on studs 335 and 336, projecting rearwardly from the rearmost guide bar 3 I 9 near the opposite ends thereof and resting on the rear tubular rail 3 I 1.

A guide bracket 342 secured at 34I to the rear face of the rearmost guide bar 3 I9 and centrally of said bar, is apertured at its outer end to embrace and shift along the supporting rail 3" and, assisted by the lower traction roll 3 3I on the front tubular rail 3I8, prevents removal of the value representing and sensing mechanism from the rails.

Spaced collars 343 and 344 (Figs. 15 and 1) secured as at 345 and 346 to the rear tubular rail 3" constitute abutments against which rest the respective outer ends of a pair of spaced centering compression springs 349 and 350 coiled about the rail 3 I1.

The opposite or inner ends of the coiled compression springs bear against sleeves 341, 348 re- 40. spectively, slidable along the rear tubular rail 3 I 9 which sleeves, in the normal position of the traveling value representing and sensing framerelapin 352 driven through the tubular rail 3I1 between the sleeves 34-1, 348 to limit the approach of the sleeves towards each other. As far as thus explained, the value representing and sensing .carriage or truck, comprising the guide bars 3I9,

320, with their supporting rolls 330, 33I, 332, 333 and 334 and guide bracket 342, and the rigid frame 3I3,' 3I4, with its rails 3I1, 3I8 secured to the case shift frame, mounted on the paper carriage, are capable. of relative longitudinal movement, the centering springs 349 and 350 on the rigid frame operating normally to maintain the value representing and sensing carriage or truck at a predetermined point on said rigid frame.

The rearmost guide bar 3 I 9 is angular in crosssection, and to its rear face near one end an angular supporting bracket 353 (Figs. 1, 2, 5 and 15) is secured'at 354, which angular bracket forms a part of the value representingmeans. The

bracket is inverted in relation to the angular guide bar, the upper flange 356 of the bracket 353 projecting rearwardly in an overhang which is slotted, as shownin Figs. 1 and 15, transversely of which-slots a supporting rod 365 extends.

The upper ends of cores 351, 358, 359 and 360 pivotally mounted on the. rod 365 are accommodated in the respective slots.

Magnet coils 36I, 362, 363, 364 surround their respective cores, the lower ends of the cores havaaearos enlargements 3'86; 361, 398 and-369 (Figs; 3, 5 and I5): formed; thereon capable of co-acting with the vertical leg of. thesupporting bracket; 353 on: closure of an; electriccircuit. The angular bracket 353" with the cores 351-360 and their windings or" coils 36t-364 constitute, in effect a multiple horse-shoe magnet. The magnets and their cores" lie, at, a; rearwardly inclined angle to the. adjacent vertical face of the-rearmost guide bar 319 (Figs. 5'- and 6), the lower ends 310; 311', 312i ami-313 respectively, ofthecoresbeingheam ed and operating as hammers to drive forwardly the horizontally arranged headed punches 314', 315', 316: and 311. These punchesare guided in corresponding horizontal holes formed in the rearmost guide bar 319 of the record makingand sensing; truck, to. intersect the vertical guide slot 323. between the guide bars 3|9, 320. Individual compression'springs 318, 319, 380; 38-1; encircling the-:st'emsof their respective punches andheld be:- tween theheads 382, 383, 394 and 385 of their punches and counter-sunk seats in theguide bar 319; normally, project the punches rearwardlyso that" their effective ends are. withdrawn from the guide slot323. The springs also press the lower fteeendsiofthe cores" 310-313 rearwardly clockwise around the bearingrod 365 (Figs. 3"and-5) until" the upper ends of the magnet coils contact the overhanging flange of the supportingbracket, so that the parts normally lie in the. positions shown in Fig. 5.

A dovetailed slot is; formed. longitudinally of the frontguide face of the, rearmost guide bar 3119, al'onga horizontal plane one linespaceabove the line of punches 31.4-31111 This seat accommodates a correspondingly formed. lining 386 (Figs.,1, 3, 5- and 15) Of an. insulating material helda'gainst displacementby a screw 381 (Fig; 1'). Aibus bar 388 (Fig. 15) pressed into the lining 386 is capable of co -acting withcontact pins 389, 390, 3.9:!" and 392 (Figs; 2 and 21) mounted for longitudinal movement in; small bushings 393, 394; 395" and 396, Fig. 5, pressed into insulating sleeves 39.9, 400, 4M and 402 (Figs. 2, 5 and 16).. The insulating sleeves 399 to 402. on their parts are pressed into. corresponding holes, formed transversely of the. perforator carriage front guide bar 320. These holes extend horizontally through the stem of the inverted L-shaped front guide' bar and open into the leading-inslot 323 formed between the apposedvertical faces of the guide'bars 3l9, 320. The holes in the base of the guide bar 3|9 which accommodate the punches 314-311' likewise extend clear through the. base of said guide bar and open at their forward ends on the, record card slot 323. The leaf springs 403'; 404,405,406 (Figs. 2.and 5) fixed on the front face of the foremost guide bar 320 betweeninsulating plates 401, 408, 409, 410 and. screws 4| I, 4.12; 413. 414i, press the inner ends of the contact pins 389 to 392' constantly but lightly against the bus bar 388. Dies 4| 5, 6, 4| 1 and 413 (Figs. 3, 2 and. 5) are fixed at the inner ends: of horizontal outwardly flared openings 424 formed in and: extending through thestem of the inverted L-shaped front guide bar 320, in. line with the hole punches 314 to 315 already described. These punches co-act with their respective dies for the purpose of punching a record card, as hereinafter' described. A receptacle .9 (Figs. 1; 3. and 5), with which the flared outer ends, of the several holes 424 communicate, is secured by angle brackets 420' and HI (Fig. 1) welded to it. fastened at 422 and 423 to the supporting member or front guide bar' 320', which receptacle serves the sensing pin for the of the card punchings, which fall intoit throughsaidf corresponding holes 424 (Fig; 5) provided both in the housin 9 as well as in the guide bar 320. Separated from the extreme lefthand punch 382 (Fig. 16) bya distance 'nearly equal to the width of a record card (Figs.- 2-2 and 2-1) and near'the right hand side of'the-amount-representing and sensing carriage 319, 320- (left hand end as seen in the rear view Fig; 15), an inverted L-shaped supporting bracket (Figs.- 1', G and 15) is fixed to the rear face of the rearmost guide bar H9 at 426, andto the overhanging flange4-21 'of' the bracket 425a further magnet coil 42-6 together with its core 429 is guided in a, corresponding slot formed in the overhanging-flange 421'. A pivot430 on which the upper'end of'the core 42-9 ispivotally supported, passes'transversely, through the slot. The lower end'of the coil'corer42-9-is'capable of co-acting by means of its headed end 43| with a punchingpin 432 (Figs. (if and 16) longitudinally operable in a hole of the guidebar-3l9. A spring 434 encircling the punch pin between a head 433 on the punching pin 432 and a corresponding countersunk shoulder in the punch pin receiving hole formed int heguide bar 3I9, presses the head of the" punch pin constantly against the end 431 of the coil core 429 torock; the core together with the-c0i1'428- in the anti-clockwise direction round the pivot; 430; This swinging'movement is limited by" contact of the-core 428with the bevelled overhanging flange 421- of the angular bracket 425,, whereby'the-rest position of all parts acted onby the 'spring'43'4'is determined; This punching" pin 432 co-actswith a die 435 fixed in the inner end of an outwardly flaring opening I in linewiththe punching pin and extending through the-guide bar'320; when a hole is to be madein a record ca d described hereinafter. A receptacle 440 (Figs. 1 and" 6) secured by angle pieces 436, 43F to the outer face ofthe guide bar 320 at 438, 439: and communicating with the flared outer end of thehole 4 (Fig. 1) serves for the reception of the card punchings which fall thereinto through hole 441 Edge perforation sensingmechanism A. shaft 4144 (Figs. 1 and 4) extending parallel with theouter face of the guide bar 320, and journaled in lugs 442' and 443 projecting from theguide bar; carries spaced crank arms 445, and 45l fast thereon.

The crank arms 445 and 45 connected by pins 450 and 456, with the outer slotted ends of sensing pins 448 and 455, respectively, slidably mounted in horizontal apertures extending through the foremost guide bar 320.

These sensing pins 448; and 455 are spaced apart a distance nearly equal to the width of a record card, and greater than the distance between the extreme left hand and right hand punches 314 and 435.

It will= be noted that the four" contact pins 339-39-2-, lie above and in the same vertical planes with the four punches 314311, and that the sensing; pin 45 lies in a vertical plane adjacent to that in which the extreme left hand punch 43 2is located (Fig. 1).

A third crank'arm- 480 (Fig. 4) is journaled on the extreme right hand end ofthe shaft 444, said third crank arm being held by means of an adjusting collar 462 fixed, by a screw 46I on the shaft 444'. A co-acting 'crank'arm 451 is fast on shaft 444 adjacent the loose crank arm, the crank arms 445 and 451 by contact with l are each pivotally 480 byway of the friction drive the shaft supporting lugs 442 and 443 serving to prevent endwise motion of the shaft; The crank arms 451 and 460 are interconnected with one another by a torsion spring 463 arranged between them on the shaft 444, whereby the spring projects with its one end into a corresponding hole of the crank arm 451 and with its other end into a similar hole of the crank arm 460., An actuating or paper feed roll cast off lever'464 (Figs. 1, 3 and 4) is articulately jointed at 465 to a connecting member 466 guided'in its endwise movement by two guide angles 468, screwed to the already described case-shift frame end plate M2 at 461. A pin 410 projects laterally from the forward upturned end of the connectin member 466 through a corresponding hole in the crank arm 460 and thereby connects the crank arm 460 with the actuating lever 464 by way of the connecting member 466, so that the crank arm 460 is laterally displaceable in relation to the pin 410 without losing the driving connection with the crank arm 451 through the spring 463, or with the actuating lever 464 through the link 466 and .the laterally projecting pin 410.

A hanger 41I (Figs. 12 to 16) fastened at 412 to the left hand end of the guide bar 320, projects downwardly and forwardly and at its forward end, is offset to form a lug 413 pivotally supporting at 415 a dog 414 which co-acts in a manner hereafter explained, at one end of its travel, with a series of spaced apart teeth 504, 130, 122 and 13l (Figs. 12-14 and 18-21) projecting from a plate'416 fixed on the machine frame. The dog 414 at another point in its travel, co-acts with apositioning cam 411 also fixed on the machine frame 302.

The dog 414 is frictionally retained in any of the positions which it may assume, relatively to its supporting lug 413.

Contacts C28, C29 and C30 (Figs. 12, 13, 18-21 and 25) are fixed on a bar of insulating material in parallelrelation with, and mounted on the carriage frame 305 and may contact an insulated rail C3 I fixed to the machine frame.

On each of two further parallel shafts 418 and 419 (Fig. mounted between the two case-shift frame end plates 3H and 3I'2 (Fig. 3') are adjustably mounted two or several forward or card feeding rollers 480 and 48l. The end of the shaft 418 projecting from the right hand end plate 3l2 of the paper carriage I40 (Figs. 1 and 5) carries a roller 482 fast thereon, and in driving connection with a roller 484 journaled on a stub shaft 483. The latter roller 484 is also in driving connection with a roller 486 rigidly mounted on the platen shaft 485. In this case, on rotation of the platen I52 by means of the hand knob 481, the drive is effected to the shaft 418 and its rollers 482, 484, 483 (Fig. 5). The rollers 48! together with the shaft 419 are spring pressed toward the rollers 480 and thereby participate in the drive.

The differential shaft I (Figs. 3 and 11) protrudes beyond the left-hand side of the calculating mechanism housing 306 (Fig. 3). On the projecting end of the shaft I25 is fixed an arm 5l4 (Figs. 1, 3 and 11) by means of its hub 5I5 and a pin 5I6. To the lower segment-formed end 5I1 is fixed an insulating part 5I1a a metal plate 5I8 and a plate 5I9 of insulating material, Fig. 11. Contact pins 520 fixed in the metal plate 518 project through corresponding holes of the outer insulating plate 5I9. The contact pins 520 are capable of co-acting with the resilient contact fingers 52 I 522, 523 and 524.

It will be noted that the contact pins 520 are arranged in four arcuate rows from top to bottom of the segmentally shaped lower end of the pendulum-like arm 5I4, pins in a row, the pins in irregularly spaced apart, in accordance w-itha predetermined plan.

The contact fingers tween two plates 525 and 526 (Fig. 3) of insulating material which are fastened at 521 to the machine frame 302. These parts are covered up and protected on the outside by a casing (not illustrated). Y T

The mode of operation of the value perforating mechanism will be described in the following section by the aid of an example:-

Method of operation in value punching For the description of the method of operation let it be assumed that the entries are to be performed according to the record card 489 partially illustrated in Fig. 17.

It may be remarked to commence with that when the feed roll cast-off lever 464 for the lower paper feed rollers 490 and 49I, is in its normal position shown in Figs. 3 and 4, these rollers contact with the platen I52. In this position of the release 1ever 464 the pins 448 and 455 which sense the edge perforations of the account card are in their retracted or inoperative position illustrated in Fig. 19. The account card 489 (Fig. 17) of relatively stiff material, may be inserted downwardly in the slot 323 (Fig. 16) formed between the opposed faces of the guide bars 3I9 and 326 of the perforator carriage, until its lower edge as is shown in Fig. 3 lies between the rollers 480 and 48l. The account card 489, moreover, is introduced with its right-hand edge at a distance i (Fig. 1'7) from the right-hand edge of the slot 323, which distance can be indicated by amark 492 (Fig. 18). By rotating the usual knob 481 (Fig. 1) of the platen I52 the rollers 480 and 48I are rotated in the manner described under the section "Value punching mechanism, whereby th account card 489 is carried downwards in the arrow direction 493 (Figs. 3 and 5). Its lower edge is then led around the platen either by hand or by a correspondingly arranged guide plate located between the platenI52 and paper guide plate 494 (Figs. 3 and 5), where it is gripped by the front lower feed rollers 491. By rotating the knob 481 (Fig. 1) of theplaten I52 further, the account card 489 is now forwarded also through the co-operation of the platen I52 with the lower feed rollers 49!) and 49L The friction gearing or rollers 482, 484, 486 maybe proportioned so that the rollers 480, 48I have the same peripheral velocity as the platen and lowerfeed rolls 490, 49I. moved in the arrow direction 493 until it is located with its line 495 indicated in Fig. 17, at the typing line level.

7 Then the name Herman Miiller, place of residence Hamburg, and account number 32, are typed, in which operation the paper carriage and theperforator carriage shift together in letter spacing direction.

After this typing on line 495 has been effected the account card 489 is moved upwardlyby a rotation of the knob 481 (Fig. 1) until the line indicated by 496 in Fig. 17 lies at the typing height. After this upward card movement has been effected the columns I to VI of the account .card 489 are clearly visible, so that now, if this has not already been effected, the totalizers TI and that there are but four 1 each suchrow being 52I to 524 are clamped be- The account card 489. isnow to Tli (Fig. 1) can be and the tabulatorriders relation thereto.

Now the account No. "375;" the date 12.3 and the text "Per cash account in bare are typed. Then the paper carriage is tabulated to the highest denomination of the column II in 'the'manner described under the section Ta'bulating device, by pressing on thecorresponding tabulator keys, namely, the keys 0.01 and 10000, the depression of the key 0,01 or it may be any "other tabulator key, causing the carriage to skip the column I in which 'no entry is made, while the depression of'the'tabulator key 1'0000'brings the carriage into the highest denomination of the column II.

By .depressing the correspondin calculating keys I98, the value 30750,00" is typed'in the column II, and as shown in "U. S. Patent to Kamme12,236,642, April 1, 1941 (filed May 14, 1 934), is simultaneously registered in the totalizer T2, and in the cross footer CT. It may be remarked at this point thaton depression of the calculating keys I98, substantially the same operations occur as are described under the section Total-taking," and since this mechanism does not belong to the invention it will not be further described. Since the pro-setting state-control plate 50 (Fig. .3) of the totalizer T2 for the control of the kind of calculation of the cross footer CT is set in this case for addition, the value 30750,00 is registered additively in the cross footer CT. Now, by further tabulating operations the paper carriage I40 positions the column VI of the card 48,9 in the typing position.

In this column the value 30750,00 is to be cleared from the cross footer CT, and registered placed on the carriage I181 (Fig.3) adjusted in in the totalizer T6.

According to the invention, however, the value 30750,00 during the clearing operation from the .cross footer CT, is to be perforated automatically at 49-1 to 503 (Fig. 17) which is effected as follows:

First, as shown in Figs. 1216,the dog 414 pivoted on "the forwardly and downwardly projecting hanger 4'H arranged on the perforator .car- I riage, which dog, because of the tabulation of the paper carriage 305 with its case shift frame, and its perforating sensing frame IIS, 320,, ;3I1, SIB, is now located opposite to the tooth 504 of the stop bar 416 (Figs. 12 to 14 and 18 to 21) is brought manually into engagement with the tooth. As a result, the perforator carriage 319, 320, which up to the present has travelled in common with the paper carriage I40 to the left, now remains stationary while the paper carriage I40 travels farther to the left. Meanwhile in the previous common movement of the paper carriage and the perforator carriage to the left to locate the column VI of the record card .at the printing zone, and the totalizer T6 at the adding zone, the contact C28 arranged on the paper carriage I40 is brought into operative relation to the contact C31, rigidly mounted on the machine frame 302. This position is shown in Figs. '27 and 18, in which the stop bar 416, the perforator carriage SIG, 320 (Fi 12), the contact CSI, and the main drive wheel II4 for driving the totalizers TI to T6 are diagrammatically illustrated in heavy lines to indicate that they are hole sensing pins 448 located in the inoperative position.

not axially or longitudinally movable during the operation of printing and perforating the amount, while the parts moving to the left and now independent of the perforator carriage -3I9, m, namely, the paper carriage I40, the account sheet 489, and the totalizers TI to T6 are represented in-light lines. The account sheet 489 held on the platen "I52 by the feed rollers 490, 404 (Fig. 3) and the rollers 480, 484, on the farther travel of the paper carriage -I40-to 'thelei=t, will shift with the paper carriage, and'along the slot 323 :of the perforator carriage 319, 20, and con.- sequently changes its position in relation to the punching pins 314 to 8-H, "at each carriage step, which it can do unimpeded since the margin 'and*455 (Figs. 1 and!) are 'Now after depression-of the corresponding tabulator key which results in locating the paper carriage H0 at "the position wherein the highest denomination of the value "30750',00" is at the printing position and the corresponding totalizer Wheel is in mesh with its master wheel, in manner described under the section Tabulating device, the total-taking "key indicated by "PC (Fig. 1) is depressed, to initiate the total-inking operation in the manner described under the section Total-taking. The value '80750110" registered in the cross footer "CT is thereby automatically cleared denomination by denomination out of the cross footer, :and registered in the totalizer T6, .located in operative position relatimely to its master wheel. Coincident therewith the value or amount is likewise automatically typed in the column VI of the card 489 (Fig. 17)

asa new balance.

In the present mechanism the typed value which in the total-taking operation, is transmitted from one totalizer to the other and s1- multaneously typed on the card 489, :is at the same time punched automatically denomination by denomination in a suitable position, for example, on the left-hand side of the card 489 (Figs. 17 and 22) The horizontal line of punches 314-311 are positioned a predetermined distance above the printing line on the sheet and on the platen I52 so that the value punching takes place between the typing 'lines of the card (Fig. 17). Therefore, the record card 489 is located for the first blank line to be typ d, by registering the proper marginal line indications m, "I22 (Fig. 17') with a suitable aligner or gage (not, shown, but common in the art). The line of punches 314131"! will then be located at such a distance from said blank line as to perforate the record card between two previously typewritten lines. In the form shown in Fig. 17, the perforated representation of the typewritten total 30750.00 at the right-hand end of the first line printed .on the body of the statement, appears on the left-hand side of the statement [just above the typewritten superscription Herman Muller, the line of perforations representing the second t tt total 3000.00 appearing just beneath .said vsuperscription. Since in the present mechanism, the perforations representing the digits 0 to 9 are formed not by ten but only .by four hole punches, 314, 315, Band 3]] (Figs. 1 and 2) it is necessary that these four hole punches are operated singly, or by .twos in the perforation of a value for the digits 0" to *9." This actuation of the hole punches is effected according to the code illustrated as a table in Fig. 39. The distance from one punch to the next in the series of four punches must also be somewhat greater than the greatest number of denominational orders of the totalizer. In the punching .ated:

26) arranged on the key lever 3, acts on the spring 501, whereby the contact point 5118 contacts with the contact point 509 of the spring 510. The same cross footer total key controlled contacts 508, 509 are shown diagrammatically in Fig. 25, to which reference is also directed. It may be remarked at this point that the two springs 508 and 510 are insulated from one another by an insulator member 511, and that the springfcontact switch 501, 510 and 511 is fastened by screws 512 to an angle piece 513 of insulating material which is mounted on the machineframe 1 by means not illustrated.

I, v The clearing of the value effected in the totaltaking results, as described in detail in the seeby the operation of the in which operation the latter makes no movement for the digit 0, while for the digits 1 to 9, it rocks with the shaft 125 progressively for nine different ex- ,tents. These rocking movements are transmitted to the contact carrying segment lever 514 vfast on the same differential shaft 125 with the differential segment 82.

. n, therefore, the first digit of the value I 30' 150,00" of the first entry is cleared from the "cross footer CT, the toothed segment 82 (Figs.

.3 and 11) and with it the contact carrying seg-' ment arm 514 are rocked counter-clockwise (Fig.

.3) four steps or increments of movement under .control of the cross footer totalizer wheel in the tens of thousands order or denomination. As a ,result, the segmental contact carrier 514 will have positioned the proper contact point (3 in Fig. 25) in engagement with the finger 523 of the four parallel contact fingers 521-524 (Figs.

3, 11, and 25-) which contact fingers are arranged in the paths of the .ltacts 520 on the rocking contact carrier. After the contact carrier 514 has come to rest in this I advanced position contact C32 (Fig. 25) is closed by the insulated fOllI arcuate rows of COD.-

1) arranged on the con- 22 (Figs. 3 and 25), and 530, The circuit follows: from the contact plate 528 (Fig.

closed contact C32, thence to main contact plate the selected contact point through the contact finger which operates its punch 316 to perforate the record sheet 489. From the punch magnet, the circuit returns traveling carriage contact C28 (Figs. to the stationary contact to maintain the contact of the carriage across column VI, and through the total key controlled contacts 508, 509 to the source 532.

Parts of this circuit are temporarily closed and incident to'each machine cycle, as by the Fig. 1, operated at each rotation of the shaft 22, and also at the points between the four re- 521-524 and the four arlocates the successive denomina- 489 at the printing point, at which time, the contacts C28 and C31 are engaged, and the de- 520, effected at each cal- 7 counter-clockwise pending contact carrying arm5 l 4 is rocked under control of the successive cross footer totalizer wheels 66 bearing significant digits to select the punch magnet or magnets 361-364 which will effect a perforation on the record sheet 489 representing the value of the digits onthe successive totalizer wheels. In the example given, the magnet coil 363 is energized, whereby the core 359 (Figs. 1 and 15) with the enlargement 368 is attracted to the stem 353 of the inverted L- shaped supporting bracket (Figs. 1, 3, 5 and 15). The end 312 of the coil core 359 thereby acts on the head 384 of the punching pin 316 forcing the punch forwardly against the tension of the spring 380 and in the opposite direction to the arrow 533 (Fig. 1'1) to perforate the card 489. A hole 491 (Fig. 22) for the number 3 has therefore been formed in the card 489. The punched-out disks pass through thehole 424, into the receptacle 419, and thus cannot fall into the machine so as to interfere with the mechanism.

The contact plate 528 (Figs. 1 and 25),arranged on the continually rotating shaft 22 and contact fingers 529, 530 remain closed for a short time only and when the circuit is interrupted at this point, the coil 363 with its core 359 and the punching pin 316 are immediately returned into their initial ositions by the spring 380 so that the punching pin 316 is withdrawn from the card 489, after which the carriage step follows after typing the number 3, in the column VI of the card 489, the number having been cleared from the cross footer CT. The paper of punches mounted on the perforator carriage.

which according to what has been said above, is

held fast in its position-because of the arresting engagement of the dog 414 with the tooth 504 of the stop bar 416, see Figs. 12-16 and 18. Now the second digit 0 of the value 30750,00 is cleared from the cross footer CT, and registered in the totalizer T6. In this operation the toothed differential segment 82 (Fig. 3) is permitted no travel, and hence the contact carrying arm 514 does not rock to interrupt the normally closed connection between the pair of contact pins- 520 in the extreme right hand vertical row of pins corresponding to the digit 0 and the contact fingers 521 and 522, and after the contact C32 is closed in the manner hereinbefore described, the following circuit is closed: 531, C32, 518, 520, 521, 522, punching magnets 361 and 362, 028,031, 508, 509, and 532. The magnet'coils 361 and 362 are energized andthe cores 351 and 358 (Fig. 15) are attracted against the action of the springs 318 and 319 in; the manner hereinbefore described, so that thecard is perforated as shown at 498 (Fig. 22) with two spaced apart perforations corresponding to the digit 0. It will be noted that the spacing between the two'perforations 498 is much greater than the spacing'between adjacent perforations, or otherwise, stated, the perforations 498 are separated by a space several times greater than the diameter of a perforation.

Furthermore, contrary to the usual typing operation, the last-named perforations 498.- are made at a point in the record sheet some distance to the left of the first-named perforation 491.

After, as above described, the punching pins 314 the digit 0 typed in the column VI of the card 489, a further carriage step takes place, which positions the card one step farther to the left. The totalizer wheel registering the digit 7 of the value 3075890 in the cross footer CT is brought-to zero by the "toothed segment 82, durin which the contact carrying arm l4 rocks counter-clockwise seven steps to enable the contact pins 528 corresponding to the digit 7 to make connection with the contact fingers 52l and 524, so that after the contact'C32 is closed the current takes the following path: 53I, C32, 518,528, 521,524, magnet coils 36| and 364,028, ml, 588, 589 and '532. The cores '351 and 368 (Figs. 2 and of the magnet coils 36! and 364 npon energization of the coils, are rocked counter-clockwise ('Fig. 5), whereby the punching pins 314 and 381 are driven in the opposite direction to the arrow 533 against the tension ':,of the springs 318 and 381, to perforate the record sheet 489, as at 499 (Fig. 22) to represent the digit '1 consisting of two holes. This digit "7" is now typed in the column VI on the card 489 after the contact-C32 has previously been reopened and the punching pins 314 and. 311 returned into the initial position by the springs 318 and 381, that is, they are withdrawn from the card 489, The paper carriage I48 with the card 489 escapes another step to the left: Attention is directed to the fact that the two spaced-apart perforations 499 which together represent the digit 7 have been applied to the record sheet, the one to the right of and immediately adjacent the left hand one of the perforations 498 representing 8 whereas the remaining perforation forming part of the representation of the digit 7' is located a considerable distance to the right of the first perforation 4'91 representing the digit 3.

it will be observed that the foregoing perforations representing the digits 3, 0 and 7, respectively are all arranged in a single straight line, the representations being interspersed and notjfollowing each other in the order of applica- 'tion, 'i.-e., in the order in which the perforations were formed.

Also -it will be noted that no perforations are formed in the record card to represent zeroes above the digit of highest order, or otherwise stated, only the digits of the amount or value are represented by "perforations.

In rderto provide for any succession of digit values from "0 to 9 in any ordinal relation,

. it is necessary to arrange the four perforating .jpunches 814-311 at such relative distances apart as to avoid overlapping the perforations irrespective of the value and ordinal succession of the digits constituting an amount.

It is also desirable to use perforating punches of as small diameter as will permit of accurate sensing.

It has been determined that any combination of digit values and denominations can be accommodated in a one-high horizontal line of interspersed perforations by spacing the successive punches apart from their adjoining punches .a ,distance equal to'the diameter of one perforation times the number of totalizer wheels in the totalizer, the diameter of a perforation being slightly less than the length of a letter space. Assuming a cross footer totalizer having ten totalizer wheels, the punches 314, 315, 316 and 311 will be spaced apart a distance somewhat greater than ,ten times the diameter of apunch hole, that is to say, aspace sufficient to accommodate ten perforations in a single row is left between each :two successive punches, .or in other .words, space between adjacent punches is greater than the width of the totalizer or of the combined orders thereof, with which the punches are associated, to prevent overlaping of perforations, "Now the digit 5 of the value 3075090 is cleared from the cross footer CT, whereby .the contact-carryingarm5l4 rocks counter-clockwise adistancecorresponding to this digit, and there. byconnects thecontact pins-528, associated with the digit 5; with the contact fingers 52! and 523. As soon as the contact C32 is closed, the current takes the path 53I, C32, 5I8, 521, 1,523, magnet coils 361 and 363, C28, C3I, 588, 589, 532. The magnet coils 361 and 363 are energized, whereby their cores 351 and 359 are attracted and drive the punching pins 314 and 316 against the tension of their springs'318 and 388 to .perforate the record sheet 489, as at 588 (Fig. 22), with two spaced-apart holes to represent the digit '5. 0n the corresponding typing of the digit *5 the carriage with thecard 489 isagain shifted to the left-one step after the contact C32 has "been previously re-opened, and the punching pins 314 and 316 returned into their initial positions. Now the next digit 0 of the value of 30'750,00 is cleared out of the cross footer CT in which operation the same mechanisms are actuated as in the clearing of the foregoing 0 in the thousands denomination of the value 30750,00. The card 489 is perforated as at 58! '(Fig. 22) which corresponds exactly to the perforation 498 only that it is punched on the card 489 in a position displaced by the corresponding number of carriage steps that is to say, the two perforations 50i representing zero are spaced apart horizontally exactly the same distance as are the perforations 498 representing the zero of higher denomination, but the pair of perforations 58l are located three steps to the right .of their corresponding perforations 498, respectively.

,And it will be noted that the perforations 581 and 498 although representing the same character, in the same amount, are relatively interspersed. The carriage I48, after the 0 is typed in the column VI of the card 489, escapes to the comma position of the value 30750,00 of the column VI of the card 489 in the typing position, but this position is skipped by the commaskipping mechanism described in the section fcomma-skipping device. No punching is effected in the punctuation or comma position on the card 489. After this, the two Os after the comma punctuation point are cleared from the cross footer CT, whereby the same mechanisms are actuated as in the case of the zeros already cleared from the cross footer CT. The paper carriage 1.48 is moved two steps farther to the left, while the two zeros after the comma of the value 3 075 0,00 are typed in the column VI of the card 489 and the card is twice perforated, as

at.582 and 1583. The punchings 582 and 583 corresponding exactly to the punchings 498 and -58 i, only that these are punched in the card 5489 at corresponding carriage step distances apart. As soon as the last digit of the value -,30,75,0,00 is cleared from the cross footer CT, .the total-taking control key I is automatically released in the manner described under the title "Total-taking, whereby the switch 588 and .589

'(Fig. 26),:is automatically opened. The opening of the switch 588, 589 after completion of the total .taking is necessary, since in the rest posiswitch 508, 509 remaining continued the machine frame 302,

tact C30 is in connection 'C3I. In this position tion ofthe contact-carrying arm I4 the contact pins 520 corresponding to the digit "0 are con stan-tly in connection with the corresponding contact fingers 52l and 522. In the event of the closed after total-taking has been completed, the punching pins 314 and 315 would be continually operated, since the contact C32 is constantly opened and closed alternately by. the continuously rotating shaft 22. Itwould be possible, therefore, if the switch 508, 509 were not opened, for a punching to be punched on thecard 489 correspondin to the thatdoes not correspond to the value 3015090 cleared by total-taking from the cross footer CT, so that therefore in the testing later described under the title Sensing mechanism .of the punched value, errors would arise. Since,

ashereinbefore described, the perforator carriage 3i9, 320 was locked by the arresting dog 415 and the tooth 504 against farther advance on the arrival of the paper carriage I40 with the column VI of the card 489 in typing position or at the beginning of the total-taking operation, the spring 350, (Fig. 12) has been tensioned in the advance of, the paper carriage movement tothe left, during the total-taking, whereby the card 489 paper carriage I40 has moved freely to the left in the slot 323 of the arrested perforator carriage 3I9, 320. Thespring 350 is progressively compressed between the collar fast on the cross rod 3I1 and the bracket arm 342 of the arrested perforator and sensing carriage 3I9, 320 as the paper carriage I40, of which cross rod 3l1 forms a part, advances step by step to the left in the typing of the total amount in column VI, The

. paper carriage I40 is now manually returned to its extreme right-hand position. In the first part of this movement of the paper carriage to the right the perforator carriage M9, 320 is pres vented from accompanying the paper carriage by the still tensioned spring 350, until the loose collar 341 associated with the opposing spring 349- contacts the bracket arm 412, whereupon the perforator-sensing carriage is spring-bolstered collar 341 to accompany the paper carriage I40 as the latter returns into its initial position which forms its rest position. During the time when the paper carriage I40 is returning relatively to the perforator and sensing carriage 3I9, 320, the record sheet 489 inserted in the paper carriage I40 travels, to the right in the slot 323 of the perforator, and takes up the position illustrated in Figs. 1 and 18. In the farther combined movement of the paper carriage and the perforator and sensing carriage to the right the stop pawl 414 moves away from the stop tooth 504 and ratchets over the teeth 130, 122, 13I (Fig. 13). Shortly before the termination of the carriage movement to the right the perforator carriage 3I9, 320 is prevented from moving farther to the right by contact of its hanger whilst the paper carriage travels farther for one or more carriage steps (a distance it, Figs. 13 and 16), to its extreme right-hand position. The spring 349 is thereby tensioned, while the card 489 travels to the right freely for the distance it in the slot The perforator carriage 3I9, 320 and the paper carriage I40 together with the card 489 now occupy the position shown in Fig.

with the contact rail the card. 489 is located with forced by the 41I (Fig. 28) against the stop 411 fixed to r 13, in which the confollowing the movement of the the extreme left-hand hole of the punching 491 to 503 (Fig.22) at the distance i (Figs. 11 and 22) to the right of the punching pin 314. Now, if in this position the switches 508 and 534 (Fig. 25) are actuated, the switch 508 of course independently by the manually operable total key lever 3, the following circuit is closed: from the source 532 to the manually closed total key controlled switch 508,509, thence through the carriage controlled contacts C3I, C30 (the carriage being at its right hand limit of travel Fig. 13) to the magnet coil 36I operating the punch 314 for punching perforations representing the digit 1,? and to the magnet coil 428 (see also Figs. 6 and 15) for operating a unch which perforates test holes in the right hand margin of the record sheet. The magnet coils 36I and 428 are energized, whereby their cores 351 and 429 are attracted to the supporting members 353 and 425, and rock counter-clockwise on their pivots 355 and 430. They thereby act with their ends 310 (Fig. 5) and 43l (Fig. 6) on the punching pins 314 and 432 (Figs. 1, 5 and 6) and push these through the card 439 against the tensions of their springs 318 and 434, whereby a further punching 535 (Fig. 22) is effected, which consists of one hole each on the two sides of the card at the edges or margins thereof. These marginal perforations 535 (Figs. 11 and 22) are formed in exact alinement with the value-representing holes 401 to 503, and correspond in regard to the distance between their tance between the sensing pins 448, 455 (Fig. ,4) which as hereinafter described serve :as line finders and determine the position of the card upon its insertion with relation to the printing and perforating mechanisms as well as its relation to the sensing mechanism for controlling the printing mechanism. The arrest of the perforator carriage before the paper carriage I arrives in its extreme right-hand position, according to the foregoing, enables the utilization of the extreme left hand punch 314 hitherto employed in forming value representing perforations, to also form the left hand marginal locating hole 535 in the record sheet 489. Hence the punch 314 performs dual operations.

After the circuit is interrupted by the opening of the switches 508 and 534 (Fig. 25) and the perforating punches 314 (Fig. 5) and 432 (Fig.6) with their associated parts return to normal position under the influence of the springs 318 and 434, the card 489 is taken out of the machine. This is effected as in the introduction of the card 489, by corresponding rotation of the platen I52 and by way Of the platen-shaft operated gear train 482, 483, 486, (Fig. 5) and the forwarding rollers 480 and 48I. After the removal of the card 489 the same is laid aside for the purpose of effecting the next entry.

Sensing mechanism The shaft 22 (Figs. 3 and 9), is extended to the left, and at the left-hand side is mounted in bearings in the left side frame 536 of the machine frame 302. On the shaft 22, a toothed wheel 531 is secured by a pin 539 through its boss 538. The toothed wheel 531 is in engagement with a toothed wheel 540, which by means of its boss 54I and a pin 542, is fixed on a shaft 30. On the shaft 30 which constantly rotates,la cam 543 is loosely mounted by means of its boss 544, and is capable of acting on a lever 545. The lever 545 together with two further levers 54B and 541, held at the necessary distance in relatwo holes, with the dis-
